Firefox slow? Limit history size for speed improvement

My beloved Firefox seems to have gotten kind of bloated and slow lately, particularly when starting it up. If you’ve experienced a similar decrease in Firefox’s startup performance, check out this quick tip from Mac Tricks and Tips. One of Firefox’s default settings is to remember 90 days of history. This means that Firefox is maintaining a list of every site you’ve visited along with the date and time of the visit for every day from the last three months. If you’re anything like me, this can be a pretty huge list.

The tip is to simply go into the Privacy tab of your Firefox preferences and lower the history setting from 90 days to something much smaller, like 5 days. To realize immediate gains, ensure your Clear Private Data settings are set to clear history, then have at it. It may take a few moments, but once your history is cleared, Firefox should start to feel like its sprightly self again.

While the tip originated at a site focusing on Macs, there’s no reason to think it wouldn’t also help when running Firefox on Windows or Linux.
